New York City is again spraying dangerous pesticides to kill mosquitoes said to be carrying West Nile Virus. The City is spraying “Duet”, which is a stronger pyrethroid poison than the chemicals it’s been spraying in recent years. "Duet" adds the synthetic chemical Prallethrin to the toxic stew of Sumithrin, piperonyl butoxide, propane, napthalene, and trimethyl benzene. According to the No Spray Coalition which had won its lawsuit against the City’s spraying ten years ago, pyrethroids are endocrine disruptors and are extremely dangerous to all people as well as animals and pets, and especially to children.
